DescriptionGitHub Advisory

bulk_extractor is a digital forensics exploitation tool. Starting in version 1.4, bulk_extractor’s embedded unrar code has a heap‑buffer‑overflow in the RAR PPM LZ decoding path. A crafted RAR inside a disk image causes an out‑of‑bounds write in Unpack::CopyString, leading to a crash under ASAN (and likely a crash or memory corruption in production builds). There's potential for using this for RCE. As of time of publication, no known patches are available.

AnalysisAI

bulk_extractor digital forensics tool starting from version 1.4 has a heap buffer overflow in its embedded unrar code that can be triggered by crafted RAR archives.

Technical ContextAI

bulk_extractor's embedded unrar library (since v1.4) has a CWE-122 heap buffer overflow when decompressing RAR archives, exploitable by crafting a malicious RAR file that triggers the overflow during forensic analysis.
